Title: Fuel assembly mixing grid with flow deflector mixing vanes
Inventor: WENCHI YU
IPC: G21C3/352
Filed: 2015-11-30
Abstract: A fuel component stirring-mixing lattice provided with fairing-type stirring-mixing vanes, comprising an outer band (10) and multiple inner bands (11). The multiple inner bands (11) intersect each other to form a grating structure. The grating structure is provided with multiple hollow grating units (110). The outer band (10) encloses the periphery of the grating structure and is fixed with the inner bands (11). The grating structure is provided with multiple stirring-mixing vanes (12). The stirring-mixing vanes (12) are extended into the grating units (110) and a surface of each of the stirring-mixing vanes (12) facing the interior of the grating units (110) is provided with a diversion groove (120). The fuel component stirring-mixing lattice is capable of reducing diversion of a coolant towards the left and right of the stirring-mixing vanes, thus restricting unordered fluid flow, providing a fairing effect, and ensuring an effect in which the stirring-mixing vanes increase the thermal headroom of a fuel component.

Title: Large-scale image tagging using image-to-topic embedding
Inventor: ZHE LIN
IPC: G06F16/58
Filed: 2017-12-14
Abstract: A method of calculating the relevance of tags applied to images involves receiving an image 314 with associated tags, which may be user-applied tags. The tags are used to create a weighted word vector 218, also known as a soft topic vector, which represents the dominant concept among the keyword tags. Visual features 312 of the image may be used to create an image feature vector 310 which can then be aligned in a common embedding space. The aligned vectors can then be used to calculate a relevancy score for each tag as it pertains to the image. The visual features may be determined with a convolutional neural network. The weighted word and image feature vectors may be aligned using cosine similarity loss. Each tag may be assigned a word vector representation and a weighted average of the word vectors can then be used to generate the weighted word vector.

Title: Calling party validation
Inventor: PAUL GRAY
IPC: H04L29/06
Filed: 2018-03-21
Abstract: In order to confirm that a telephone call received on a first connection 16 is from a trusted party 10, the called party 12, 13 connects over a second, independent connection 17 to a server 15 associated with the trusted party 10 and shares a PIN code with the server. The called party transmits the code over the first connection (e.g. using DTMF tones) and, if the connection is genuine, it is intercepted by the server which generates a message to the called party over the second connection confirming that the code has been matched. This gives the called party assurance that the call is from a party 10 associated with the trusted server 15. If a rogue caller 20 attempts to call, the shared code will be routed over the rogue caller's connection 26, so no match will be identified by the server. Confirmation of a match may only be given if it occurs within a set time period after sharing the code. The code may be generated by the called party or the server. In another embodiment, the server communicates the intercepted code over the second connection for the called party to perform the code comparison.
